Line Up and Sit Down is a great ability.
For bows: Horizon Walker's T5s are higher damage than Mechanic T5s, and the HW capstone is solid when combined with low hanging FE feats in Falconry, HW, VKF and Shiradi. If you have Ranger levels, the capstone gets even better. T4 Mechanic is higher damage than T4 DWS though.
Mechanic still needs an EF/NHB equivalent boost though.
